Are you constantly prompted to register your device on a Wi-Fi network, even after you’ve already done so? This issue might be related to the Private Address feature on your iOS or Android device. Introduced to enhance privacy, this feature can sometimes interfere with network registration systems that rely on consistent MAC addresses. This guide will walk you through how to disable the Private Address setting on both iOS and Android devices to ensure seamless Wi-Fi connectivity.
Understanding Private MAC Addresses
Before diving into the steps, let’s briefly understand what Private MAC Addresses are and why they might cause connection problems. A MAC (Media Access Control) address is a unique identifier assigned to your device’s network interface. Traditionally, each time your device connected to a Wi-Fi network, it would present the same MAC address.
To improve user privacy, Apple and Android implemented a feature that periodically randomizes your device’s MAC address for each Wi-Fi network. This means your device uses a different, “private” MAC address every time it joins a new Wi-Fi network, or sometimes even when rejoining a network it has connected to before.
While this enhances privacy by making it harder to track your device across different networks, it can cause issues with networks that use MAC address registration for access control. Networks like “eduroam” or “UT-Open,” often found in educational institutions and public spaces, might require device registration based on the MAC address. When your device uses a private MAC address that changes, the network might see it as a new, unregistered device each time, prompting you to register repeatedly.
To resolve this and ensure consistent network access, you may need to disable the Private Address feature for specific Wi-Fi networks. Here’s how to do it on iOS and Android devices:
Disabling Private MAC Address on iOS (iPhone, iPad, iPod touch)
If you are using an iPhone, iPad, or iPod touch running iOS 14 or later, follow these steps to disable Private Address for a specific Wi-Fi network:
-
Open the Settings App: Locate and tap the “Settings” app icon on your home screen.
-
Navigate to Wi-Fi Settings: Scroll down and tap on “Wi-Fi.”
-
Access Network Details: Find the Wi-Fi network you are connected to (e.g., eduroam or UT-Open) or the network you are trying to connect to. Tap the “i” icon (information icon) next to the network name.
Alt text: Information icon next to a Wi-Fi network name in iOS settings, indicating where to tap for network details.
-
Toggle Off Private Address: Look for the “Private Address” or “Private Wi-Fi Address” option. It will likely be toggled on (green). Tap the switch to turn it off (grey).

-
Reconnect to the Network: After turning off Private Address, your device might disconnect and reconnect to the Wi-Fi network. If it doesn’t reconnect automatically, manually select the network from the Wi-Fi settings menu.
Once you have disabled Private Address for the specific network, your device will use its actual, physical MAC address when connecting to it. This should resolve the repeated registration prompts and ensure stable Wi-Fi access.
Disabling Randomized MAC Address on Apple Watch
For Apple Watch users experiencing similar issues, you can also disable Private Address directly on your watch:
-
Open the Settings App on Apple Watch: Press the Digital Crown to access the app menu and tap the “Settings” app.
-
Go to Wi-Fi Settings: Scroll down and tap on “Wi-Fi.”
-
Select the Network: Tap on the name of the network you are connected to (e.g., eduroam or UT-Open). If you haven’t connected yet, swipe left on the network name and tap the more button (…).
Alt text: “More” button indicated by three dots in Wi-Fi settings on Apple Watch, used to access network options.
-
Disable Private Address: Tap “Private Address” to turn it off.
Disabling Randomized MAC Address on Android Devices
The process for disabling Private MAC Addresses on Android can vary slightly depending on your device manufacturer and Android version. However, the general steps are similar:
-
Open the Settings App: Access the “Settings” app on your Android device.
-
Navigate to Network & Internet or Connections: The exact wording may differ. Look for options like “Network & Internet,” “Connections,” or “Wi-Fi & Network.” Tap on the relevant option.
-
Go to Wi-Fi Settings: Select “Wi-Fi” to access your Wi-Fi settings.
-
Access Network Options: Find the network you are connected to or want to modify (e.g., eduroam or UT-Open). Tap the gear icon or settings icon next to the network name. In some cases, you might need to tap and hold the network name or simply tap on the network name itself to access more options.
-
Find the Private Address Setting: The location of the Private Address setting can vary. Look for options like:
- “MAC Address Type” or “MAC Address Format”: If you see this, tap it and choose “Device MAC” or “Phone MAC” instead of “Randomized MAC” or “Private MAC Address.”
- “Privacy”: Look for an “Advanced” or “Privacy” section within the network settings. You might find an option like “Privacy” or “MAC Address Type” here. Select “Use device MAC” or “Phone MAC.”
- “Advanced”: Sometimes the setting is hidden under “Advanced” options within the network settings.
Common paths include:
- MAC Address Type > Device MAC
- MAC Address Type > Phone MAC
- Advanced > Privacy > Use Device MAC
- Advanced > MAC Address Type > Phone MAC
-
Select Device MAC Address: Choose the option that indicates using the “Device MAC” or “Phone MAC” address. This will disable the randomized or private MAC address for that specific network.
-
Reconnect to the Network: Similar to iOS, your device may disconnect and reconnect. If not, manually reconnect to the Wi-Fi network.
Note for Google Pixel Watch Users: Currently, Google Pixel Watches use Randomized MAC addresses, and as of the last update, there is no user-facing option to disable this feature. Therefore, Pixel Watches might face compatibility issues with networks requiring MAC address registration until Google provides a fix or update.
Conclusion
Disabling the Private Address or Randomized MAC Address feature for specific Wi-Fi networks can be a necessary step to ensure consistent connectivity on networks that rely on MAC address-based registration. By following these simple steps for your iOS or Android device, you can resolve persistent network registration prompts and enjoy uninterrupted Wi-Fi access. Remember to only disable this feature for networks where you are experiencing issues, as the Private Address feature generally enhances your privacy on public Wi-Fi networks.
